Hi TI guys,

I know a special JTAG sequence can erase IPE. However ,if E-fuse is programed and JTAG is denied to access the memory.

Can BSL erase the IPE through incorrect BSL-passwords ? If it doesn't work, anyother soulution? Thanks.

UART BSL can mass erase this device back to factory state.

Hello SeaFesse,

According to the user guide, "By default, on most MSP430 bootloaders, an incorrect BSL password results in mass erase of the device. The mass erase causes all code to be erased".

Thanks,

Yiding
